20 Claims.

The present invention relates to linecasting and composing machines andmore particularly to such machines when operated automatically andequipped with apparatus for quadding and centering assembled lines ofmatrices during the casting operation.

,An object of the present invention is the provision of a Control unitarranged with elements responsive to predetermined control signals forselectively operating quadding and centering attachments of thelinecasting machine to present the assembled lines of matrices inaccordance with their operation to the casting chamber.

During automaticline composition, it is frequently-desirable to obtainstaggered line justification, sometimes referred to asquadded lines, inwhich assembled matrices with or without space bands are moved either tothe right or to the left in order to obtain a stepped effect, as in thecase of newspaper headline composition. In three-line columns, thecentral line is preferably centered, the first line moved to the left,and the third line to the right. In certain other cases, as inconcluding partial lines of paragraphs, it is desired to quad the linefragments to the left. In obtaining the above and other quaddingoperations in connection with automatic line composition, it isproposed, in accordance with the provisions of the present invention, toobtain the quadding operation during the presentation of the assembledlines at the casting chamber and to shift the assembled lines ofmatrices thereat so as to present the casting intaglio into a positioncorresponding to the quad selection control.

Accordingly, the present invention contemplates the provision of a pairof floating vise jaws presented on opposite sides of an assembled lineof'matrices that has been delivered to the casting chamber in front ofthe mold disc. An operating train deriving power from the principal camshaft of commercially well-known types of linecasting and composingmachines is selectively associated with each of the floating vise jaws.The application of power is controlled by a shiftable rack in accordancewith the predetermined positioning of which a universal connector iscorrespondingly arranged communicating the operating power with eitheror both of said vise During a predetermined instant preparatory-to thecasting operation, either or both of said jaws are moved, shifting theassembled line of matrices. rightwardly, leftwardly,or in centralposition. In order that the terms quad-right or quadding to the rightand quad-left? or quadding to the left may be clearly understood as usedin the following description, it may be stated that quadding to theright may also be described as spacing to the right, which actioninvolves the provision of spaces at the right-hand end of a slug and isaccomplished by movement of the right-hand vise jaw to position the typecharacter matrices and the space bands to enable the casting of a blankslug portion at the right. Conversely,quad-left or quadding to the leftmay be described as spacing to the left. It is accomplished by movementof the left vise jaw, and results in a blank space at the left of theslug In a quadding operation, a vise jaw moves opposite to thedirection, the name of which it bears. Thus in quadding left, aquad-left vise jaw moves to the right and in so doing moves assembledmatrices and space bands to the right, and in quadding right, thequad-right vise jaw, matrices and space bands move to the left. If theassembled matrices and space bands upon delivery to the casting positionshould accidentally assume the proper position for a predeterminedquadding operation, they may suffer no movement under the influence of avise jaw, but the quadding operation will involve movement of a vise jawin the direction outlined above.

In accordance with a preferred embodiment of this invention, the controlis governed by the alternative energized condition of a set of operatingsolenoids energized in accordance with quadding signals. The signals arepreferably effective through the instrumentality of a record readermechanism and selectable control elements as particularly disclosed anddescribed in Patent No. 2,091,286 granted August 31, 1937, to Howard L.Krum et al, Where linecasting machines are adapted for both automaticand manual keylever control, means are also provided for manualoperation of the appliance embodied in the present invention. The threeclasses of quadding signals as above described, after being initiatedeither through automatic or manual control, are thereafter stored in aset of primary storage relays, following which, under the control of theelevator mechanism associated with the casting apparatus, they aretransferred to the corresponding relay located in a secondary storagebank while the primary bank is restored to normal condition forreception of a succeeding quadding signal.

The transfer of a quadding signal from the primary bank to the secondarybank coincides with the advancement of an assembled line of matricesfrom its composing level to its delivery slide level where, as is wellknown in commercial line composition machine structure, an assembledline of matrices may momentarily be suspended to await the readiness ofthe casting apparatus. Upon the transfer of an assembled line ofmatrices from the delivery slide level to the casting chamber, thequadding signal stored in the secondary storage relay bank iscommunicated to an operating solenoid, which signal is then efiectivefor the ultimate purpose of correspondingly adjusting the universalconnector described above and for effecting the proper response on thepart of either or both quadding vise jaws. Accordingly, "the quadding orcentering control is incorporated into the linecasting machine operationunder automatic supervision of a record reader control unit whichperforms the line composing functions as well as the collateral controlfunctions incident to line composition.

For a more comprehensive understanding of the present invention,reference may be had to the accompanying drawings and to the followingdetailed description wherein similar reference characters indicatecorresponding parts throughout, and wherein:

In Fig. l, the reference character |I refers generally to an automaticcontrol unit that is provided with a record reader mechanism whichcomprises a plurality of selectable elements some of which are allottedto the execution of the functions of matrix release, others to theexecution of various collateral functions such as rail shift, elevatoroperation, etc., but three or four of which are particularly concernedin. connection with the supervision and control of the apparatusembodying the present invention.

In Fig. 4, three automatically selectable elements relating to thepresent invention are indicated I2, I3, and I4. The element I2 isassigned to the control of the left quadding. In response to itsselection, the left-hand vise jaw in the casting mechanism is made tomove the assembled line of matrices to the right side casting position.In inverse manner, the selection of element I4 moves the right-hand visejaw so as to shift the assembled line of matrices to the left. Upon theselection of the intermediate selectable element I3, however, both visejaws in the casting apparatus are actuated simultaneously, effecting acentering of the assembled matrices and distributing the available spaceequally in a manner that may be understood more comprehensively by areading of the following detailed description.

A set of three manual control keys I5, is, and I1 parallel the threeautomatic levers I2, I3, and I4 in arrangement and operation, eachaffording a means for manually initiating a response in the quaddingVises similar to the response produced. by their corresponding leversI2, I3, and I4. A selecting signal originating by the actuation ofeither manual key I5 or automatic lever I2 closes a circuit beginningwith positive potential source I8 or I9, passing through the contactpair 2| or 22, then continuing over common line 23 to the line 24,winding of quad-left primary storage relay 25, to ground at 25. Theenergization of relay 25 attracts its four armature contactors 21-29 and3|. Contactor 21, upon closure with its contact point, completes alocking circuit originating with positive current source 32 andcontinuing over line 33, contact pair 34, line 35, contact pair 36,lines31 and 38, the contact and armature 39, line 4|, armature 42 andits associated contact line 43 to the contact and armature 21, thenceover line 44, through the filament of signal lamp 45, winding of relay25, to ground at 2B.

In a similar manner the actuation of manual key I6 or automatic lever I3sends an energizing impulse over line 45 to the centering relay 41 ofthe primary storage relay bank. This relay is similarly provided withfour armature contactors indicated 48, 49, 42, and 5|. The lockingarmature 48 of relay 41 lies in the circuit originating with positivecurrent source 32, line 33, contact pair 34, line 35, contact pair 35',lines 31 and 38, contact and armature 52, line 53, armature 29 and itsassociated contact, line 54, armature 48 and its associated contact,line 55, the filament of index lamp 50, winding of relay 51 to ground55.

Likewise the actuation of manual key I1 or automatic lever I4 transmitsa control pulse over common circuit 56, line 55, through the winding ofquad-right relay 51 to ground at 58. This relay controls a set offourarmature contactors59,6 I 52, and 39. Its locking armature 55 is ina circuit originating with positive source 32 and continuing over line33, contact pair 34, line 35, contact pair 36, line 31, armature 3| andits associated contact, line 62, armature 5| and its associated contact,line 63, armature 59 and its associated contact, line 64, filament oflamp 65, through the winding of relay 51 to ground at 5B.

Thus the locking armature of each relay 25, 41, and 51 is in the circuitwhich includes also a contact located under the control of each of theother relays 25, 41, or 51. In this way the storing of a signal in theprimary storage bank in one of the relays 25, 41, or 51 prevents theconcurrent operation of any of the other of these relays until such timesubsequent to the storage operation when the particular signal istransferred from the primary storage bank to the secondary storage bank.

To understand the utility of this transfer, it should be borne in mindthat coincident with the transmission of a quadding signal there is setup in accordance with the composing mechanism control an assembled lineof matrices in the assembly elevator 66 which the particular quad signalis to modify. The assembled line of matrices must not at once proceed tothe casting chamber but may instead await its sequence. This delay iscaused by a characteristic operation of commercial types of linecastingmachines whereby the composing mechanism is adapted to entertain aparticular line of composition at the ber and in which a third line isbeing entertained in the casting chamber'proper and is activelyperforming the slug casting operation. Since three lines of compositionmay at the same instant be in various stages of progress, it isnecessary that means be provided for storing their three associatedquadding control signals.

Accordingly, the most recently composed line finds its associated signalin the primary storage relay bank aforedescribed, the intermediatewaiting line of composition in the secondary storage relay bank, whilethe active line finds its signal already communicated to the operatingsolenoids. In the case of relays 25, 41, and 51 and associated controlcontacts 28, 49, and 6|, each when brought into engagement with itscontact point prepares a path originating at positive current source 32,line 61, contact pair 68 and line 69, which in turn communicates withthe three armatures 28, 49, and 6I parallelly. Separate circuits II, 12,and 13 extend from the contact points controlled by armatures 28, 49,and 6|, respectively, to individual secondary storage relays such as'14,15, and 16. Line 1I continues through the winding of relay 14 to anindividual ground 11, line 12 through the winding of relay 15 to aground 18, and line .13 through the winding of relay 16 to a ground 19.Each of the secondary relays 14 to 16 is provided with a locking circuitfor maintaining it closed after the signal transfer operation has beenconsummated. These looking circuits are traceable from positive current7 potential 8|, contact pair 82, line 83, contact pair 84 to common line85, from which separate circuit branches are obtained leading to thecontact points of the armatures 86, 81, and 88. The individual circuitsleading from the armatures then continue through associated filaments ofindex lamps 89, through the windings of their respective relays, totheirassociated grounds 11-19.

The operating contacts of the secondary storage relays are controlledthrough the medium of their armatures 9I, 92, and 93, respectively. Theleft-quad relay 14 prepares an operating circuit from positive currentsource 94, through armature 9I and its associated contact, line 95 tothe winding of an operating solenoid 96, thence through a common returnwire 91, contact pair 98, to the ground 99. The right-quad relay 16 inlike manner prepares a circuit originating at I98, depending upon thepreceding condition of the switch control lever I 99, which in turn isdependent upon the preceding operation of either of the solenoids 96 orI93. f

If the preceding quad signal was a left-quad control signal, solenoid 96was the last to have been operated, leaving the main control lever I I Iin its counterclockwise extremity as illustrated in Fig. 4, lever 'I IIbeing'pivotable about point II2 as a center. With the main lever III inits counterclockwise position, a projection II9 carried thereby engagesone side of the forked end would remain in its clockwise extremeposition,

shifting lever I99 in a reverse direction so that shuttle switch I96contacts with point I91. Under this condition the circuit I95 istraceable from this point over line II3 to the opposite centeringsolenoid II 4 which thereafter functions to move main operating leverIII from its extreme clockwise position to its centering position. Asset forth in the preceding paragraphs, control lever I99 may bepresented in either of two controlling conditions with respect toshuttle switch I96, motion to either of these two controlling conditionsbeing imparted by projection I I9 of main control lever I I I. Retentionof lever I99 in its extreme clockwise and counterclockwise positions isaccomplished by the spring shown in Fig. 4. The noted spring isdistended between spring posts and is effective as the lever I99 isrocked from one or the other of its control positions. Movement of leverI99 is thus completed following its initial motion by lever III.

In accordance with the present embodiment, the centering solenoids H4and H6 are illustrated as being independent elements for moving leverIII from either of its extreme positions to its central position. Theabove result may also be obtained by providing circuit connectionsbetween the solenoids 96 and I93 for energizing them concurrently andfor thereby centering the main operating lever I I I. The manner inwhich lever III is controlled is therefore viewed as merely subservientto the particular linecasting machine structure and to the convenienceof individual operators. The essentials of the present invention arepredicated therefore upon the provision of means for controlling athree-condition quadding mechanism by means of three selectable elementsof an automatic control unit, the specific arrangement being largelydependent upon the particular type of quadding mechanism to which thecontrol is to be applied.

The movement of the main operating lever II I is transmitted through theloose link connection II1 to a control rack bar II 8, see also Figs. 1and 2. The rack bar II 8 may ordinarily have associated with it a manualcontrol lever such as H9, and is capable of three positions representedby the three detent notches into which the jockey bell crank I2Ipresents itself alternatively. The opposite end of rack bar II8 carriesa rack toothed segment I22, which cooperates with a rack pinion I23 bestillustrated in Fig. 3. The pinion I23 is carried by a stub shaft I24 onthe opposite end of which there is secured a beveled gear I25 thatmeshes with a corresponding beveled gear I 26 carried by the verticaloperating shaft I21. The ratio between gears I25 and I26 is such that inaccordance with the three horizontal positions of rack bar II8, themotion transmitted to shaft I21 causes it to rotate through 180, itsintermediate position being 90 from either one of. its extremepositions. Noting now the illustrations of Figs. 6 to 9,

it will be observed that the shaft I21 and the connector I28 carried byit are capable of three conditions of operation, one of which is furthermodified giving a total available selection of four conditions. Fig. 6illustrates its condition during right-quadding position. At this timethe right-hand lever I29, through its stud ICII, being operativelyengaged with the connector I28, is then presented within the groove I32,see also Fig. 5. When in this position, the upper flange I33 ofconnector I28 is presented so that its portion of greater radiusoverlies the stud I3I while its diametrically opposite portion which iscut away as at I39 clears the stud I34 of left-hand vise lever I35. If,under this condition, the vertical operating shaft I2! is thrustdownwardly cyclically, motion is imparted to right-hand lever I29 butnot to left-hand lever I35. This rotates lever I29 about its center I36counterclockwise, causing its associated lever arm I3! to move theright-hand vise jaw I38 leftwardly, thereby effecting what is known as aright-quad operation, the assembled matrices being presented on the leftextremity of their available line space.

When the universal connector is rotated into a position such as thatillustrated in Fig. 7, which is known as the centering position, bothstuds I3I and I35 are engageable by the flange I33. Under this conditionof. operation the cut away section I39 is presented at the right end andis ineffective. If the vertical operating shaft I21 now is moveddownwardly, both lever arms I25 and I35 are effective for moving theirvise jaws I38 and I42 through the medium of lever arms I5I and IfiI, sothat the assembled line of. matrices is centrally disposed with equalspace indentations on both ends of the line.

The position indicated in Fig. 8 is known as the left-hand quaddingposition. In this case the universal connector I25 is 180 from itsposition as illustrated in Fig. 6. Here the cut-away portion I35 is inregistration with the stud I3I of right-hand lever I29, while theopposite stud I34 of the left-hand lever I35 underlies the flange I33.Hence, when the'vertical operating shaft I2! receives its cyclicmovement, the left-hand operating lever I II alone is actuated, movingthe assembled line of matrices rightwardly into the left-hand quaddingposition.

Since it is not always essential or desirable that the quadding vises beeffective, means are provided whereby both Vises may be disassociatedconveniently and without altering materially the condition of theseveral operating parts. The inoperative position is shown in Fig. 9.Here the universal connector I28 is presented in the same position as inthe case of Fig. 8. The right-hand operating lever I29 is thendisassociated by virtue of the cut away portion I39, but in order torender the left-hand vise lever I35 inoperative, its engagement lug I35is withdrawn. It will be noted that lug I54 is longitudinally shiftablein its supporting boss I43 and is provided at its opposite extremitywith a grooved flange I44. A lever I55, pivotally supported at I46 in astationary portion of the casting mechanism has inte= grally formed withit an arcuate segment Idl that is adapted to be received within thegroove of flange MI. The arc of segment I41 has a radius coincident withthe pivotal center Hill about which the left-hand vise lever I35 isrotated. Thus, during the reciprocation of lever I35, the groove offlange I44 is at all times operatively connected with segment I41,which, as explained above, is supported from a stationary portion of themachine.

The operating rod IZ'I which, as described before, receives a periodicvertical motion, is connected through the coupling I49 with a lever I5Ipivoted at I55, Figs. 1 and. 2. A main operating lever I52 pivoted atI53 is cyclically actuated by the apex of a cam I55 working inopposition to a return spring I58. The cam I55 is carried by the maincam shaft I55 of the principal machine and its apex encountersthefollower roller I51 of lever I52, causing its opposite arm, actingthrough a compression spring I55, to impart clockwise motion to thelever I5I, thrusting downwardly the end coupled at I59 to the rod I21.The contour and timing arrangement of cam I55 is preferably such thatlever I52 is reciprocated counterclockwise, lever I5I clockwise, and rodI27 moved downwardly at a time shortly after a line of matrices has beenpresented in casting position, the reverse operation following shortlyafter a slug has been cast. The compression spring I54 serves to absorbthe motion and avoid rupture in the event that the free movement ofshaft IZ'I or lever I5! is restrained.

In order to better understand the'sequence of operation of the severalsignal storage elements as related to the line composing apparatus andthe condition of several assembled lines of matrices which may be foundin various stages of progress as explained above, a brief rsum of theoperation will now be had.

Operation It will be supposed that the line composing and castingmachine is operated at the peak of its efliciency, under which conditiona particular line of matrices is being assembled in the assemblerelevator 66; a preceding line of matrices is awaiting delivery and ispresented at the level of the line delivery slide IfiI, while a thirdline of matrices is being entertained within the casting mechanism.Accordingly, three quadding signals are stored; the first in the primarystorage relay bank, the second in the secondary storage relay bank, andthe third having been just received in one or another of the operatingsolenoids 95, I53, H4, or IIIi. To diversify the illustration, it willbe supposed that the three lines constitute a stepped headline whereinthe first with the intermediate line of matrices that is awaiting on thedelivery slide level is stored in the relay [5 of the secondary storagebank, it having reached that position during the elevation of itsassociated line of matrices by the assembler elevator 55 and transfer ofthe line to the line a delivery slide IISI as a direct result ofprevious energization of primary storage relay 47 in response toselection of member I3 or operation of key I5. Thus relay I5 isenergized during the occupation of the casting position by the precedingline. The signal that is to be associated with the final line or the onethat is just completing composition is stored in the relay 25 of theprimary storage relay bank.

7 Following this condition, the first elevator I59 begins its ascent fordelivering the matrices which have completed their cooperation with thecasting mechanism to the distributor elevator when the roller I62, Fig.4, comes into engagement with the contactor of contact pair 98, closingthe latter and completing the circuit, which occurs when the firstelevator reaches its intermediate level. A circuit is completedoriginating in the particular case at the positive current source I94and continuing through the armature 92 and its associated contact point(because relay is energized), line I65, shuttle switch I06, contactpoint I01 (because the main switch III was last in its clockwiseextremity), causing lever I09 to be presented in its counterclockwiseextremity, thence over line II3, through the winding of solenoid II4,common return line 91, contact pair 98, to ground at 99. This causes theenergization of solenoid II4 which moves main operating lever III fromits extreme clockwise position to its central position, moving rack barII8 accordingly from its left-hand position to its intermediateposition. The movement of rack bar II8 causes the universal connectorI28 to shift from a position such as. that illustrated in Fig. 6 to thatillustrated in Fig. 7.

Meanwhile, the first elevator I59 has delivered its line of matrices tothe distributor elevator and the line delivery slide I6I has beenreleased to move the intermediate line of assembled matrices intoposition withthe first elevator. When this occurs, a roller I63 carriedby the slide'I6I comes into engagement with a projection I64 which actsupon the bell crank I65 for opening the contactor I of contact pair 82to break the common locking circuit which had been holding relay 15energized at point 82, permitting its armatures to be released. Upon itsreturn, the delivery slide rides off the projection I64, permittingagain the closure of the locking circuit. Upon the return movement'ofthe line delivery slide, its delivery slide arm which is interlocked incontrol with the assembling elevator in a manner more fully described inPatent No. 2,091,286 granted August 31, 1937 to Howard L. Krum et al.permits the release of the assembling elevator 66 with its assembledline of. matrices; As soon as the elevator 66 starts its ascent, aroller I 66 carried thereby cams lever I61, causing the closure ofcontact pair 68. This completes a circuit which had been prepared by theenergization of relay 25,traceable from positive current source at 32,over line 61, through the contact pair 68, line 69, armature 28 i andits associated contact (which is closed at this instant because of theenergization of relay 25),

line 1|,

The prepared circuit is maintained in condition winding of relay 14 tothe ground 11.

for completion by reason of the continued energization of relay 25 froma locking circuit traceable from positive current source at 32 throughcontacts 34, over conductors 35, 31, and 32, contact and armature 39 ofrelay 31, conductor 4I, contact and armature 42 of relay 41, conductor43, contact and armature 21 of relay 25, lamp 45, andwinding of relay 25to ground 26. Thus the signalstored in relay 25 is efiectuallytransferred to its associated secondary storage relay 14. The relay 14,once energized, is maintained locked l over the common locking circuit85, 83, etc., de-

scribed above.

When the elevator 66 attains the line delivery slide level, itencounters an insulated block I68 associated with the contactor ofcontact pair 34,

' opening the common locking circuit which had been holding relay 25energized. Upon the return of elevator 66, the locking circuit isreestablished in readiness for a succeeding quadding signal to bedelivered by the manual keylevers I5, I6, and I1 or automatic controllevers I2, I3, or I4. As soon as the elevator 66 returns to its matrixassembling level, line composition is resumed in accordance with therecord reader control described in the copending application referred toabove, and as this line is completed, another quadding signal may bereceived by one of the levers I2, I3, or I4, which, upon its closure ofits associated contact pair 22, introduces an impulse that is stored inthe primary storage relay bank.

Thus it will be understood that the present invention contemplates aseries of signal storage systems operative progressively to associatecertain modifying signals with their related lines of matrices which inturn are also stored in the course of various steps between their linecomposing position and their casting position.

For purposes of rendering the storage system more readily controllableand adjustable, manual unlock keys are provided for breaking the lockingcircuits and permitting the reinsertion of alternative quadding signalsin the place of particular signals which it may be desired to change.For example, in the primary storage relay bank, one such key indicatedI69 is provided in the circuit originating with positive currentpotential 32, line 35, and contact pair 36. Key I69 opens the contactpair 36 upon its operation and, upon its release, permits thereengagement of the contact pair, whereupon an alternative signal may beinstalled uponone of the relays 25, 41, or 51, manually.

In a manner similar to that aforedescribed, the quadding signal storedin the secondary storage relay'bank may be deleted by the actuation ofrelease key I1I, which acts upon the contact pair 84 of the commonlocking circuit originating at positive current potential 8| To changethe quadding signal associated with the particular line of compositionalready entertained in the casting chamber, it is but necessary, ofcourse, to shift the manual control handle II9 from any particularposition to any other.

While the present invention has been explained and described incontemplation of a specific embodiment, it will be readily understoodthat numerous modifications and variations may be incorporated withoutdeparting from the spirit or scope thereof.
